    • EK60 Water Column Sonar Data Collected During EX2201

    Metadata Updated: November 10, 2022

    From February 23 - March 3, 2022 (Pascagoula, MS to Key West, FL), NOAA Ocean Exploration conducted a shakedown of the remotely operated vehicle (ROV), video, telepresence, and sampling operations as well as mapping and positioning systems aboard NOAA Ship Okeanos Explorer. The ROV engineers tested and calibrated ROVs Deep Discoverer and Seirios' ROV motor controllers, auto position software, lighting system, hydraulic system, ME-20 low-light camera, high-definition ancillary ROV cameras, sector-scanning sonar, as well as tested remote-piloting capabilities of ROV Deep Discoverer. Shakedown and readiness operations for the EM 304 multibeam sonar included a GNSS Azimuth Measurement Subsystem (GAMS) calibration, Patch Test, speed-noise test, coverage extinction data collection, and integration and testing of the newly installed SeaPath 380-R3. In total, the expedition team conducted 7 ROV dives ranging from 480 to 3,420 m depth and collected 4,930 square kilometers of acoustic data during transits and calibrations. The expedition explored the West Florida Shelf and the Straits of Florida offshore the U.S. southeastern coast. The expedition confirmed the location of a shipwreck target, thought to be a 19th century whaler. Corals and sponges were observed 4 out of the 7 surveyed dive sites, with 3 of the 7 containing high diversities of benthic species. A total of 12 samples were collected: 3 geological, 3 biological, and 6 commensal (not including blank samples).
